Heating and Cooling grants
75 listings tracked right now · page 1 of 2
Grants and schemes for heat pumps, district heating and clean cooling. The cheques come from UK DESNZ (heat networks and the Boiler Upgrade Scheme), the US DOE, EU LIFE and Horizon, and utility and municipal heat programmes. Listed below are the open heating and cooling grant calls in that landscape, taken from each funder's own notice and re-checked on every refresh.
Buildings funding is split between retrofit delivery, which is usually distributed through local authorities, housing providers and national schemes, and building-technology innovation, which comes through Horizon Europe, Innovate UK and the national energy agencies. Retrofit money is normally tied to a specified housing stock and a delivery partner, so the eligibility question is generally which stock rather than which technology.
This page lists open heating and cooling grants currently tracked by Raise Lens — 75 of them right now, sorted with the soonest deadline first. Every listing has been classified against the sustainability taxonomy rather than matched on keywords, so what appears here is heating and cooling work rather than anything whose description happens to mention it.
The funders publishing heating and cooling grants here include Dept for Energy Security & Net Zero, Energimyndigheten (Swedish Energy Agency), 50135547, among 2 others. Who is funding matters as much as what: eligibility, reporting burden and the realistic timeline to a decision vary far more between funders than between individual calls.
Geographic coverage on this page spans GLOBAL, GLOBAL-SOUTH, NORTH-AMERICA, EUROPE. Eligibility is usually tied to where the work happens or where the applying organisation is registered, and the two are not always the same — worth checking before investing time in an application.
1 of these close within the next 30 days. Deadlines are taken from the source listing and re-checked on every refresh, but the originating funder remains the authority — always confirm against the official notice before you submit.
